Next: org-begin org-end

It seems that this is best pushed somewhere else. I.e. next to the
`wrap-code' functions.
Looks like there's plenty of room for simplification once the
stack-oriented label juggling is pushed deeper.
Especially the org code is a bit of a hack. It probably also just
works using dummy names.
Maybe `wrap-word' and `wrap-variable' should have an optional org
argument?
